Pros & Cons

Pros

✓ V30/U3 rating sustains 4K Ultra HD and Full HD recording without dropped frames
✓ Rated up to 100MB/s read and 50MB/s write for fast footage offload
✓ 256GB rated for up to 600K recording hours (over 68 years) in TEAMGROUP testing
✓ Resists extreme temps, shock, water, static electricity, and x-rays

Cons

✗ 50MB/s write is half the read speed, so large file copies to the card are slower
✗ 600K-hour figure assumes a low 200KB/s bit rate, far below 4K bit rates
✗ UHS-I bus only, with no UHS-II path for faster transfers
✗ 2-year warranty is short for a card marketed on 68+ years of recording

Manufacturer description

If you run a security camera, doorbell cam, or other always-on recorder, the TEAMGROUP High Endurance 256GB microSDXC card is built for that constant rewrite cycle. It carries UHS-I, U3, and V30 ratings, so it can sustain 4K Ultra HD and Full HD video without the slowdowns and dropped frames that standard cards can hit under continuous recording. TEAMGROUP rates the 256GB card for up to 600K hours of recording, which is more than 68 years. That figure comes from testing in a WYZE Cam Pan v3 at a 200KB/s bit rate, so expect less recording time at higher bit rates, such as 4K. Rated speeds are…
